Every time I try to search for something nothing happens.
No suggestions load and I don't get any results..
I can't seem to figure this out for the life of me..

I just used the sdk examples and tweaked them as needed
Here's the source code

Function SearchScreen()
    InitTheme()

    print "start"
    'toggle the search suggestions vs. search history behavior
    'this allow you to generate both versions of the example below
    displayHistory = false
    history = CreateObject("roArray", 1, true)
    'prepopulate the search history with sample results
    'history.Push("the old paths")
    'history.Push("good news of the kingdom")

    port = CreateObject("roMessagePort")
    screen = CreateObject("roSearchScreen")
    'commenting out SetBreadcrumbText() hides breadcrumb on screen
    screen.SetBreadcrumbText("", "search")
    screen.SetMessagePort(port)

    if displayHistory = true
        screen.SetSearchTermHeaderText("Recent Searches:")
        screen.SetSearchButtonText("search")
        screen.SetClearButtonText("clear history")
        screen.SetClearButtonEnabled(true) 'defaults to true
        screen.SetSearchTermHeaderText("Suggestions:")
    else
        screen.SetSearchTermHeaderText("Suggestions:")
        screen.SetSearchButtonText("search")
        screen.SetClearButtonEnabled(false)
    endif

    print "Doing show screen..."
    screen.Show()
    print "Waiting for a message from the screen..."

    ' search screen main event loop
    done = false
    while done = false
        msg = wait(0, screen.GetMessagePort())
        if type(msg) = "roSearchScreenEvent"
            if msg.isScreenClosed()
                print "screen closed"
                done = true
                screen.close()
            else if msg.isCleared()
                print "search terms cleared"
                history.Clear()
            else if msg.isPartialResult()
                print "partial search: "; msg.GetMessage()
                if not displayHistory
                    screen.SetSearchTerms(GenerateSearchSuggestions(msg.GetMessage()))
                endif
            else if msg.isFullResult()
                print "full search: "; msg.GetMessage()
                history.Push(msg.GetMessage())
                if displayHistory
                    screen.AddSearchTerm(msg.GetMessage())
                end if
                Print "Delta"
                searchResults(msg.GetMessage())

                'uncomment to exit the screen after a full search result:
                done = true
                screen.close()
            else
                print "Unknown event: "; msg.GetType(); " msg: ";msg.GetMessage()

Have you actually debugged this in the debug console? There are two issues that I see, both with the "alpha" check in GenerateSearchSuggestions.

1. You've misspelled "alpha" as "aplha" which will crash with a "Use ofun initialized variable." error.


2. searchconn() returns either an array or a string, but you're checking to see if the value of alpha is (not) equal to a specific string ("Can't parse feed"). If searchconn() successfully returns a search results array, then this check will crash with a "Type mismatch." error.

If you change that line to the following, it should work:

if islist(alpha) then

You have a similar issue in your searchResults() function. You also have a typo in the StreamUrl node of your search XML. And, you really should URL encode the search text before appending it to the search URL.

No, I didn't debug..My friend loads them for me cause I don't have a Roku.
I didn't even think of a type mismatch error..It does make way more sense to test it with islist() though.
Thank you! I t works great now!
